i have a 2gen 13bt street ported like 4kmiles on motor, im using a safc, with 680cc injectors what turbo would make my car run naste fast, im looking for about 320+hp on like 15/17 psi

 

grab up a little t04b with a .81/84 p-trim turbine and an h-trim compressor. that'll do the trick at around 12 psi. you could even go with a t3 hot side if you wanted, but might as well leave yourself some room to grow.

one pair of 680's won't be enough fuel, though. 680/720 combo should work just fine.
